A jötunn (also jotun; plural jötnar; in the normalised scholarly spelling of Old Norse, jǫtunn /ˈjɔːtʊn/; or, in Old English, eoten, plural eotenas) is a type of being in Germanic mythology. In Norse mythology, jötnar are often contrasted with gods (the Æsir and Vanir) and with other non-human figures, such as dwarfs and elves, although the groupings are not always mutually exclusive. The entities included in the jötunn category are referred to by several other terms, including risi, þurs (or thurs) and troll if male and gýgr or tröllkona if female. The jötnar typically dwell across boundaries from the gods and humans in lands such as Jötunheimr.
The jötnar are frequently attested throughout the Old Norse records, with eotenas also featuring in the Old English epic poem Beowulf. The usage of the terms is dynamic, with an overall trend that the beings become portrayed as less impressive and more negative as Christianity becomes more influential over time. Although the term "giant" is sometimes used to gloss the word "jötunn" and its apparent synonyms in some translations and academic texts, this is seen as problematic by some scholars as jötnar are not necessarily notably large.
